Horrible Harry
Harry loves horrible things — slime, snakes, gross schemes — and his loyal best friend Doug narrates the chaos from Miss Mackle's class in Room 2B. Suzy Kline's chapter books were Scholastic order-form gold, and if you remember it as Room 3B, you're not wrong: the class moves up to third grade in the later books.
Suzy Kline's "Horrible Harry in Room 2B" launched in 1988, illustrated by Frank Remkiewicz, and the one everyone remembers followed a year later: "Horrible Harry and the Green Slime" (1989). The formula was perfect first-chapter-book fuel: a second-grader who loves horrible things — slime, snakes, worms, elaborate gross-out schemes — narrated by his best friend Doug, with the real drama living in the everyday texture of Miss Mackle's classroom (secret pals, science projects, cafeteria intrigue). The series later moves the kids up to third grade in "Horrible Harry Moves Up to Third Grade," which is why plenty of readers remember the series as Room 3B even though it starts in 2B.
The books felt lived-in because they were: Kline was a real elementary teacher, spending over two decades teaching second and third grade at Southwest Elementary in Torrington, Connecticut, and the classroom detail came straight from her day job. More than thirty Horrible Harry books were published, a core staple of 90s Scholastic book-club catalogs and classroom shelves, often sharing space with her other series, Herbie Jones.
